To make progress in understanding the world and each other it is necessary to be flexible. It must be assumed that audiences and readers are familiar with our words, semantics and syntax. Sometimes clear definitions are desired, but these can also only be described in words. As already indicated in the posts about Wittgenstein and Gödel, there is more than can be expressed with words and formal systems. As long as we are still searching for understanding and truth, openness is necessary. Therefore, the brief descriptions below of the main concepts used here should not be taken strictly and may change over time. Links to the corresponding Wikipedia entries are also provided for reference.
